JIAWANSHUN Coffee Roaster Upgraded Electric Coffee Bean Roaster 1.1lb Coffee Roaster for Home Use,0-240℃ Temperature Adjust&Timer 110-120V

My first 2 roasts were 300 g regular Uganda beans and 300 g of swp decaf Sumatra beans. I roasted outside ambient temperature 55 f. Roast profile was based on time and bean color. I tented the roaster with welding blanket due to outside temperature. Dried both roasts for 10 minutes with the Ugandan beans at 170 c on the dial and decaf at 160 c. I gradually raised the temperature on both, Uganda to 230 c and decaf to 210 c. Total roast time on Uganda was 26 minutes and decaf 24 minutes. Uganda came out a nice medium roast but the decaf was a light roast, looked medium but tough to grind. Mixed the 2 and coffee was great. On my third roast I decided to mix the Uganda and decaf Sumatra and roast them together, 150 g each. This time I decided to use infrared thermometer gun to roast by temperature. Roasted outside in 40 f with welding blankets on top and bottom of the roaster (placed roaster on cookie sheet with blanket under that). Dried the batch for 10 minutes at 170 c on the dial then set the dial to 225 c and monitored the surface temperature of the beans till they reached 415 f. Total roast time was 24 minutes, came out medium roast. Great.

Pros: Can roast up to 1.1lbs of coffee beans at once. Easy to use with adjustable temperature control. Consistent roasting results. Compact design, great for home kitchens. Cons: SMELL is very strong so expect it to linger A bit noisy during operation. The roasting process takes some time, so it’s not the fastest option. Experience: I’ve been using this roaster for a few weeks, and it’s been fantastic! It’s easy to use and gives me great results every time. The beans come out perfectly roasted, and I love the control I have over the process. Who This is For: Great for coffee enthusiasts who want to roast their own beans at home and enjoy a fresh cup every time. Final Thoughts: This coffee roaster is a great value. It’s easy to use, provides excellent results, and is perfect for anyone who loves fresh, homemade coffee!

Update 7/2024: The newer version of this roaster gets hotter, faster. 10 minutes at 170 to dry them out, 8-12 minutes at 240 to roast depending on what you like roast-wise (I like a medium roast just into second crack). The first batch will roast faster than subsequent batches. I don't use the welding blanket anymore, it gets plenty hot on its own now. Original review: This coffee roaster is so-so out of the box. It functions like an old whirley-pop popcorn maker from back in the day, with a non-stick base and a rotating blade that agitates the beans. Its major design flaw is that the glass lid, while sturdy, does not sufficiently insulate the roaster to get the beans hot enough to roast them to proper coffee roasting temperatures. You can barely get them to 200 degrees centigrade after 45 minutes or more, even at the hottest setting. However, get yourself a welding blanket (https://smile.amazon.com/dp/B019SWRT0E/) and this roaster goes from so-so to outstanding. You can roast 300 grams of green beans in about 45 minutes. I recommend setting it to about 180 degrees centigrade with the lid on for ten to twelve minutes to drive out moisture. Then, remove the lid and wipe off the condensation. Replace the lid and turn up the heat to 240 degrees. Place the folded welding blanket over the roaster. Set your timer for 30 minutes. (This is far too long on newer models; see second update) After that, come back and check the temperature (using your infrared thermometer) and color of the beans, based on roasting charts you can find on the internets. If they aren't done, continue roasting in five minute increments until they reach the desired temperature and color. A note on smoke: many reviews talk about how smoky coffee roasting is, as though your neighbors will call the fire department on you if you roast coffee. This is nonsense. Yes, there is some smoke, but it's nothing terrible. Just roast your coffee under your stove's hood, and turn the fan up to at least medium, and you should be fine. So, I knock off one star for not functioning as designed out of the box. But add a welding blanket, and this roaster works great. Green coffee beans are very inexpensive, and unlike roasted coffee beans, green beans keep for years in a cool, dry place! We haven't bought roasted coffee beans once since we figured out how to use this thing properly, and it has easily paid for itself. Update 7/2022: After just under three years, the heating element is starting to wear out on this device. Even turned all the way up, we can no longer get my coffee roasted at the stage we previously did. This seemed to happen very suddenly - one week it worked fine, the next week, not so much. So, still a great value, but it looks like we'll need to replace it soon.

Having used various roasters before, I recently pan-roasted for a few months with good if laborious results. I wanted something simpler but affordable. This unit has worked perfectly with all varieties of green beans I've tried. Running unit outside, I preheat at max with lid on for 15 mins, then add 400-450g of beans & set 35 min timer, leaving unit undisturbed. When timer goes off I check & when color is to my liking, I lift lid & use a fan to blow off chaff for a minute or so while unit runs. I try to avoid nonstick but for this I imagine stainless steel would require a lot of cleaning. The base portion stays very clean.

This product is not worth the price, maybe if it was 20.00 it would be worth a try. No automatic timer built in... My toaster oven from 1992 has a timer. It doesn't alert you when it gets up to temp. The quality of the roasting arm is cheap and the tolerances to the pan are not made well, which means you have to bend and adjust the bar so it doesn't scrape the pan, which then causes beans to go under the rotating arm which puts stress on the assembly and cause a lot more burnt beans. Would not buy again, and would not recommend.

Ok a few minor details lacking. This is my first attempt at roasting coffee beans. It seemed like the roast was a bit uneven but in the end the coffee was good. Some beans got jammed in the arm near the pivot. I scratched the non stick getting them out, my fault. Says you can adjust the arm height but doesn’t tell you how in the instructions. Time will tell about durability.

Es fácil de usar y me encanta

Ok, so forget the attached instructions... Read the reviews for best results! I was roasting Indian monsoon Malabar, quite a moist, dense bean. I messed up the first batch, but still managed to salvage it... Just a little grassy. Here's my method, great results for the past 4 batches... Preheat on full temp! 19 mins. Throw 400gm of beans in... Any more seems to be too inconsistent and uneven. Turning down to 200c-220c Wait for drying phase... 10mins approximately... Should start browning well and first crack by 15mins... Give it another 10 mins..... I switch it off right at 2nd crack... 25-28mins total time. Cool it off right away! I'll probably reduce temp and times for different types of beans!

This is a very good quality roaster for producing excellent roasted beans the way they should turn out. Read some of the other reviews where they complained but they didn’t follow instructions. I tried doing it different ways like they said which didn’t work well but when I followed the directions exactly it worked perfectly. I only roast enough for three days at a time. One thing that is important that I had to do is the rotation arms that move around the beans, it wasn’t quite flat enough. I took the nut off and bent the arms slightly until they were perfectly flat and not scraping on the heating surface. That way no small beans can get trapped under the arms. You want the arms nice and flat because then they allow the beans to distribute evenly while roasting. This is not a high volume roaster. I only make slightly less tian 3/4 of a cup of raw beans and that gives me 1 1/3 cups of Roasted Beans when I use the organic single origin Guatemala raw beans from Equator company. Also, it is best to allow the beans to cure for two days to absorb enough CO2 and enrich the flavour. They still taste great freshly roasted but that two day time thing is good. Make sure you use up the beans within 5 days after roasting! Highly recommend this machine. Good value for the price too.

楽しみで自宅焙煎をしている素人です。参考になればと思いレビューします。熱風式の焙煎機が壊れたので購入しました。なので、熱風式と比較しながら話します。この焙煎機のいいところは、音が静か、焙煎量が多い、焙煎時間が短いになります。悪いところは、焼きむらが出る、チャフの処理がいるところです。熱風式は、ドライヤーをしている時のような大きな音がします。焙煎量も最大７０gと少なく、時間も２ハゼまで２０分位かかっていました。ただ、焼きむらはほとんどなく満足いく仕上がりで、チャフもフィルターの掃除だけでした。この焙煎機は、豆をかき混ぜる音しかなく静かで、焙煎量も３００から５００ｇと多いです。３００ｇで２ハゼまでの時間は３０分弱で、量での比較で時間は短くなります。ただ、工夫をしても焼きむらが出ますし、チャフと一緒に焙煎するのでチャフを豆から分離する手間がかかります。出来上がりは満足というより妥協できる範囲内という感じです。豆がエチオピアＧ４で粒の大きさに大小あるのも原因の一つかもしれません。焙煎方法は、ずっと蓋をした状態で、まず２４０℃で１０分余熱、豆を入れて２２０℃で１０分、２３０℃で１０分、２４０℃で１０分で出来上がりです。大まかに２３分位で１ハゼ、２８分位で２ハゼがくる感じです。工夫というのは、豆を入れてから３０秒間隔で焙煎機を振って豆をかき混ぜるということをしています。焙煎機の両端を両手で持ち、前後に振ってかき混ぜています。これである程度むらを緩和することができます。チャフは焙煎豆をざるに入れ、屋外で風で吹き飛ばして分離しています。焙煎機の値段が安価なので、このような手間をかけても、私はいい買い物をしたと思っています。
